Suppose that xi and x2 are random samples of observations from a population with mean m and variances2. Consider the following three point estimators, A.B.C, of m:*1 + x2*1 + 3r2*1 + 2x2C =A =B =23a) Which of these estimators yields an unbiased estimator of m? Justify your answer.b) Of those that are unbiased, which is the most efficient? Justify your answer.
